To lll whom it may concern.'

Be it known that I, JAMES AILINGHAM,

Chicago, in the county of Cook and State of Illinois, have invented certain new an useful Improvements in Waste and '.Overflow Mechanism, of which the followingl is a specification.

This invention relates 'to certain .improvements in a mechanism -for bath-tubs, lavatories, sinks, and the like, of a somewhat similar character and construction to that shown and described in Letters Patent No. 955,740, granted to me on April 19 1910, for improvements in a valve mechanism for lavatory apparatus, and some of the obJects -of my'present invention are similar to those set forth in the above mentioned application but other objects and results -will be attained thereby, and the objects, in part, are as follows: to provide a Waste valve mechanism that' will afford means whereby the construction of the vessel, in connection with which it is used, will be cheapened and rendered more sanitary, easily cleaned and symmetrical in appearance.

Another object is to provide a mechanism of. the above described character which shall be attractive in appearance, sim lel and .inexpensive in construction,v dura le and efficient in operation with a minimum of fouling surface, Aand so made as to be readily applied to a vessel andits parts easily ad]usted as well as having manual means for cleaning the fouling surface without removing any of its parts.

Other objects and advantages of the invention will be disclosed in the subjoined description and explanation.

In the accompanying drawin serves to illustrate the invention: igure 1, is a vertical sectional view of a waste and overflow mechanism embodyingthe invention, showing the valve and its operating members in their lowered positions; Fig. 2, is a detached perspective viewof the cap which closes the upper portion of the outer tube of the mechanism; Fi 3, is a fragmentalperspective view o the combined means for operating the valve and cleaning the fouling surface of the tubes of the mechanism; Fig. 4, is a detached perspective view of the members of the jointed valve stem, showing 4said members separated;

blades for the outer tube at their lower and Fig. 6, is aplan view partly in section,taken on line 6-6 of Fig. 1,'"showing the inner or overflow tube removed from the overflow opening therein.

Like numerals of reference, refer to cor# respondingparts throughout the different .views of the drawing.`

Referring now to Fig. 1 of the drawing, the reference numeral 10, designates the valve casingof the mechanism as a whole, and the sameconsists of a 'hollow casing 11, having openings 12, and 13, in its upper and lower portions respectively, as well as a horizontally disposed opening 14, located about midway between theopenings 12, and 13. These openings are referably formed in extensions 15, with w ich the casing is provided and said extensions may be screwthreaded or otherwise adapted to engage l pipe sections or tubes for the purpose to be presently explained. Within the casing 11, is located another casing 16, betweenthe walls of which casings is formed a by-pass 17, which communicates at its upper and lower endswith the openings 12, and 13, respectively. The inner' casing' 16, extends inwardly from the openingl 14, of the outer casing, andhas a valve-seat 18, in its lower portion and an opening 1,9, in its upper part, which opening is provided with a transversely disposed bar or member 20, having a central opening 21, for the reception and operation vof the valve stem 22, which has a valve 23, suitably mounted on its lower end to open and close the opening or valve seat 18 in the inner casing. The extension 15, in which the opening 14, .is formed is adapted to be connected by means of 'a 4pipe section (not shown) to the waste opening of a batli-tub,lwashbasin, sink, or other vessel, so that the water in the vessel may pass into the inner casing 16, and it will be understood that the valve casing may be located at any suitable point with respect to the vessel, but

when the device is to be used in connection with a bath-tub, the valve casing will preferably be located at one end of the tub near the bottom thereof, and usually at that end on which the faucets for the hot and cold water are located.

In the drawing, the mechanism shown,.is especially intended for use in connection with a bath-tub, and it will be seen that a tube 24, of a suitable size, is fitted at its lower end in the opening 12, of the upper exsmaller than t e tube 24, and is extended upwardly within the latter to a suitable point near its upper end. As shown in Fig. 1, the lower portion of the valve stem 22, is extended through the opening 21, in the horizontal bar or partition 20, and has its upper end provided with a reduced portion 26, havino an elongated slot 27, to receive a pin 28, for connecting the valve stem 22, to a member 29, which has its lower portion rovided with a slot 30, to receive the reduce 26, on the valve stem 22. The u tion of the member 27, is also rovlded with a vertical slot 31, to receive va c eaning bar or blade 32, which is located in the inner .tube 25, and extends from the lower end thereof portion per porupwardly to near its upper end at which. portion it is connected to a rod 33, the upper portion of which is screw-threaded .to engage a screw-threaded socket 34, formed in the lower portion of the shank 35, of a knob or handle 36, used for operating the valve and for cleaning the inner and outer tubes. The lower portion of the blade or bar 32, is provided with a vertical slot 37, to receive the valve stem 22, so as to provide means for slight movement of said stem, for it will be understood that as the stem 22, is loosely connected to the member 29, on the blade or bar 32, the said stem will be so supported that the valve 23, will be accurately seated, should the tubes 24, and 25, or either of them be a little out of plumb. I

Surrounding the lower portion of the inner tube 25, isa collar 38, which has a pair of diametrically disposed projections 39, which are on its outer surface between which the lower ends of the cleaning blades or bars 40, are placed and secured. As

shown, these blades are located between the inner and outer tubes 25, and 24, respectively, and extended upwardly to the upper portion of the inner tube. Located on the upper end of the inner'tube 25, is a ring or collar 41, which has on its lower surface a downturned ange 42, to it'within the tube 25, and is provided on its outer surface with diametrically disposed projections 43, in pairs, between which are placed and secured the upper ends of the cleaning bars or blades 40, which as before stated are interposed between the inner and -outer tubes. The upper portion of the ring or collar 41, is provided with a number of projections 44, to engage a pin or rod 45, extended horizontally through the rod 33, just above said ring. Fitted on the upper end of the in its closed position cuter tube 24, is a vertical apertured cap 46, which has on its upper portion an enlar ment 47, provided with a horizontally (F, posed opening 48, in which opening is movably located a head or block 49, against pring 50, the

whlch rests one end of a s other end of which rests agalnst the screw 51, located in vsaid openin Fig. 1, the shank 35, of t e handle 36, is extended through the aperture 52, of the enlargement 47, and cap 46, and engages the upper portion ofthe rod 33, on which it can be suitably adjusted by reason of its screw-threaded engagement with said rod. By employing the spring pressed block or h ead 49, and the screw 51, which are located in the opening 48, of the extension 47, it is apparent that when the shank of the knob is raised the said head or block will act as a brake thereon and retain it in its raised position, yet will permit it to be easily pressed downward or turne if desired. The pressure of the block or head 49, may be regulated by turning the screw 51, in the pro er direction as is apparent.

From the oregoin and by reference to the drawing, it will ie clearly understood and readily seen that when the valve 23, is as shown in Fig. 1, the water from the vessel will enter the opening 14, of the valve casing, and as it rlses in the vessel will pass through the opening 19, of the inner casing and u through the inner tube 25, from `whic when a suiicient-quantity of water is admitted to the vessel, it will overflow into the As shown in l tube 24, and from thence pass through the' i by-pass 17, and out through the discharge opening ,13, which may have communication with a discharge pipe leading to any suitable point. By this cbnstruction, it is apparent that only one opening in the bottom or lower part to take care of the waste and overflow, and that the ordinary overiow openin in the upper portion of the vessel may be dispensed with, thus rendering the vessel more attractive in appearance and saving the expense of producing the last'named opening and furnishing the same with connections -to carry away the overflow water. In my present construction, it is obvious that the sizes of the overflow tubes can be made much smaller than ordinarily, thus furnishin a more compact and cheaper iitting, and 1t will also be understood that by virtue of the by-pass feature of. the mechanism, the dirty or soiled water will have access only to the inner or smaller tube, while the overflow from said tube will impinge only the surface `of the outer or larger tube, thereby reducing the fouling surface to a minimum. As the means for supporting the valve is both vertically reciprocating and rotatable it is evident that the fouling surfaces o of the vessel is necessary' ias i the tubes 24, and 25, can be readily scraped images or cleaned by the blades Aor bars 32, and 40,

y directly from the vessel through the inner casing 16, and from thence through the opening 13, in the valve casin It is manifest that as the rod 33, to which the handle 36, is connected is not in continuous engagement with the collar 41, that the blade 32, withinthe inner tube may be raised or rotated independently of the blades 40, but when it is desired to rotate the last named blades, this can be done by turning the handle in either direction so asvto cause the lpin 45, to strike the projections 44, which upon further turning of the handle will cause the blades 40, to Vbe turned in the f uter tube and scrape or clean its inner surace.

From the above description, 'it is obvious that the device is susceptible of considerable modiication without material departure from the principles and spirit of the invention, and for this reason I do not desire to be understood as limiting myself to the precise form and arrangement of the several parts of the mechanism herein'set forth in carrying out my invention in practice.
